  • Probability of exploitation in the next 30 days: 0.32% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.

Low priority for now. Upgrade to Unknown Eventin 4.1.22 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

The Eventin WordPress plugin before 4.1.22 does not restrict access to non-published content by status or ownership in one of its REST API namespaces, allowing unauthenticated users to retrieve draft, pending and private posts belonging to other users, along with the passwords and contents of password-protected ones.
